Answer 1

Answer 2

Explanation:

Alkali metals dissolve in liquid ammonia giving deep blue solutions, which are conducting in nature. The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light

When an alkali metal dissolve in liquid ammonia, the solution can acquire different colors,I mean dilute solutions of alkali metals in liquid ammonia exhibit dark blue color this is because of ammoniated electrons absorb energy in the visible region of light.

Alkali metals can also react with liquid ammonia to form solutions that slowly decompose to give hydrogen gas and the metal salt of the amide ion (NH2−).
